Contribution of studying the influence of cultural practices on structural stability and organic soil potential on the plain of Annaba, ?¢????North East of Algeria?¢???

Abstract

Aggregate stability has been proposed as an indicator of soil quality due to its importance in the physical degradation and its sensitivity to organic matter content. The aim of our contribution is showing the influence of cultural practices on structural stability and organic soil potential in the region of Annaba "The North East of Algeria» The comparative study is made between station which has been to traditional tillage and reduced tillage practices soil protection against cultural practices for at least five years. The results show that in soils subject of traditional tillage, the organic matter is more important, the reaction is slightly acid but the structure is less stable. On the other side in soil of the reduced tillage, the content of organic matter is higher in the surface than in depth also that the structural stability remains higher in surface than in depth. The results of our study showed that farming practices causes changes in the structure and concentration of organic matter in the soil.
